Comparative ammonia (N[H.sub.3]) losses were assessed using static sorber traps on semiarid tame pastures and native rangelands following the application of liquid hog manure using either surface banding or coulter injection at varying rates. Historical changes ill livestock production have included an increase in confinement feeding and larger concentrations of livestock (McKenna and Clark, 1970). These changes have arisen from economic factors and regulations aimed at reducing pollution. It follows that manure management must be done without excessive contribution to soil, water, or air pollution, and be compatible with efficient and timely crop production (Evans et al., ...
